[iOS] routing crash

iOS 2021.06.18.1

Routing crash between the points linked below. Crashes for all modes (walking, cycling). Varying the end point nearby can sometimes generate a "system error".

Moving the end point beyond the the gate and routing with car can generate some unusual results, including walking a back to the road to drive a short distance, when the walking solution is much shorter.

• Crash is fixed
• Car routing doesn't do fallback to pedestrian. It honestly tries to find nearby car roads ..

Root cause here is that start point is put between 2 downloadable regions and doesn't belong to any of them. That happens when region borders are not super high precise.

Expected behaviour here is if the app would say something like "Please, try to move start/end point a bit .."

@vng we can also programmatically check and align the borders :)

Not sure if this is related or new.

Well, it's not a crash in updated app version, but "System error" and seems like it's also connected with neighbour regions.
